` NIANTLE.

Application filed October 31, 1325.` Se11al.No.,66,067.

This invention relates to'mantles of the combustible tvpe, and has especial reference` to the type of mantle used in an lapparatus for the treatment of the ear4 such as the one .disclosed in the United States Letters Patent No. 1,554,876 granted tome.

One of the principal objects .of the present im'ention is the production of a mantle capable of being 4used in an apparatus for the treatment of the ear which mantle when ignited and consumed produces heavier than air Which Will descend into the ear and produce beneficial results to the ear.

Another object of the invention is to provide means for facilitating the ignition of the mantle characterized hereinbefore.

Another object of the invention is to provide a mantle of the character mentioned With means for taking up the heavy gaseous particles or impurities in the generated gas as it descends to thus obtain a clarified gas before the gas enters the ear.

Another object of the invention is to combine with a mantle of the character mentioned a holder Which supports the mantle, the mantle being treated With a chemical to render a portion thereof non-combustible, or noxious to fire, so that themantle will not burn all the Way down to one of the holder parts, and yet not interfere with the proper combustion and d-escension of the gases.

The nature of the invention and the distinguishing features and advantaees Will .appear when the following specification is read in conjunction with the accompanying drawing, in whichw Figure 1 is a side elevation of the mantle of the present invention, its holder and a portion of an apparatus for the treatment of the eur, the latter being shown in section.

F 2 is a vertical sectional viev,7 talren substantially on the line QMQ of Fig. 1 of the mantle and its holder alone.

Fig. 3 is a perspective View of the outer mantle element. K

F ig. t is a perspective View of the inner mantle element.

Referring now more particularly to the several views of the drawing it Will be Yap@ parent that, there is shown a mantle 10 supported by a holder 11 which is capable of being used in an apparatus for the treatment of the ear, a portion of which is designated at 12. A comprehensive showing and description of the nature and advantages of the apparatus inV Awhich the mantle of the present invention is used appears in the Letters Patent hereinbefore referred to. The mantle 10, in the present instance, is made of two elements, an element 18 .and an element 14l-. rllhef-elementl is made up .of a piece of white, .preferably Woven, fabric of single ply and is formed into the shape of a truncated cone. The element l-hasgood capillary and absorbtive 'properties and is capable of being consumed vWlgien ignited. lThe fabric from Which thel element 13 is made is. Saturated with alcheign'cal which produces heavy gases when ignited. In the present instance the fabric is saturated with a hydrocarbon of the Marsh gas series having the formula CnH2n+2- The chemical is applied to a portion of the fabric fromr the brim so as to occur from the brim down substantially tivo and one-half inches, the portion being indicated at 15, and the remaining portion 16 is treated with a suitable chemical Which renders the same noncombustible,'and renders the same safe and closes the pores so as not to permit air to enter at the bottom of th-e mantle or tointerfere with the combustion and descension of the gases generated. The element 14 is made preferably of a single ply of fabric, and also formed into the shape of a truncated cone slightly smaller than the element 13 so as to lit closely Within-the same. The

fabric from which the element 14 is made isv of Wider mesh -so that the' strands thereof will be far enough apart 'to provide interstices, or a slight rough surface that'ivill cover the entire inside of the mantle. rlhe fabric from which the element la 'is mad-e has good capillary and absorbtive properties and is capable'of being consumed when ignited. The fabric from which the element 14 is made is not saturatedy but is utilized for taking up heavy carbon impurities which i collect on the rough surface thereof to thus 10 may be made in any preferred manner to permit the gases to descend, and in the present instance consists of a nipple 18 having screw threads 19, there being a frame 2O connected to the nipple 18. The frame 20 is made of Wire and consists of diverging members 21 and ring members 22 arranged transversely of the members 21 and connected thereto. The frame 20 is arranged vvithin the mantle 10, as shovvn most clearly in Fig. 2, and the lower end of the mantle extends into the nipple 18 and is attached thereto as at 23 in any preferred manner. The frame 2O prevents the mantle from collapsing as it is being consumed. The man-- tle is connected in the apparatus by virtue of the threaded end of the nipple 18 being lscrewed into a part of t-he apparatus, as shown in Fig. 1.

When it is desired to generate the gases, the tabs 17 are ignited andas a result the mantle Will burn and be consumed, the gases Vgenerated being heavier' than air and Will descend into the ear. The mantle will be consumed down to the portion 16, which, as stated, is non-combustible, thus-means is providedv for permitting only the desired kind of gas to enter the ear being treated. Vhat I claim is 1. A mantle for use in an apparatus for the treatment of the ear, consisting of a combustible material saturated With a chemical which When ignited generates gases heavier than air and said material also being treated with a chemical to render a portion thereof non-combustible. Y 2. A mantle for use in an apparatus for the treatment of the ear, consisting of tivo plies of material, one of the plies being combustible and foraminous, and the other ply7 being combustible and surrounding the former ply and saturated ,with a chemical which produces gases heavier thanY air, and the outer ply of material also being treated Wit-h a chemical to render a portionthereof non-v combustible.
